Abstract
Allogeneic stem cell transplantation (alloSCT) has become available for elderly patients or for patients with comorbidities by introduction of reduced-intense conditioning. Comorbidity-related prognosis after alloSCT can be estimated by the hematopoietic cell transplantation comorbidity index (HCT-CI). The charts from 85 patients who have undergone 90 alloSCTs between 1999 and 2011 were analysed. Most patients received a dose-reduced conditioning and a graft from an unrelated donor. Patients were stratified for age, HCT-CI, cGvHD versus no cGvHD, and a modified HCT-CI with a further split high-risk score. Age over 60 years did not affect the outcome. Manifestation of cGvHD improved the prognosis significantly. An additional stratification of the high-risk group of the HCT-CI revealed that even a fraction of these patients can have considerable benefit from an alloSCT. Furthermore, this high-risk collective could be clearly discriminated into two groups with different outcomes. The investigation confirms that age is no absolute risk factor for alloSCT and demonstrates the heterogeneity of the high-risk group of the HCT-CI. A comprehensive investigation of an additional stratification is suggested. Furthermore, the authors encourage early withdrawal of immunosuppression, even in elderly patients and patients with comorbidities to permit graft-versus-leukaemia/lymphoma, since cGvHD is associated with a significantly better prognosis.
